I play on a laptop and have therefore not so insane amount of screen area available: 15.6 ". For controlling the spaceships in Elite: Dangerous, this product has proven to be indispensable as the head controller to expand the visible area 4 times the size at least. Who wants to encircle already with 3 screens - and creates without wars with the girlfriend trouble ;-) It is also much more natural if the view from the cockpit automatically mitschwenkt, especially when you have to keep the enemy in the eye, without wanting to change the flight direction of the own ship. Although of course you have to keep your eyes on the screen - that bothers me personally only from time to time in the border area then. Tracking is very smooth and accurate, and I think it's good that the supplied bracket ranges - which is wireless and easy to attach to the cap. Every now and then the camera was daytime confused by scattered light - I mostly play in the evening and the problems could be as far as ever deal.
